DAX give different outputs when I expect the same

[KristinG]

Hi! I need som help here 

Value from selected date = 

CALCULATE(

        SUM('Table1'[AMOUNT]),

        ALL('Calendar')

        'Calendar'[DateKey] > MAX('Calendar'[DateKey]))

Value from selected date in prev year = 

VAR CurrentMaxDate = MAX('Calendar'[DateKey])

VAR StartDate = EOMONTH(CurrentMaxDate, -12)

RETURN

CALCULATE(

    SUM(Table1[AMOUNT]),

    ALL('Calendar'),

    'Calendar'[DateKey] > Startdate)

The measures shoud give the exact same output if I enter May 2024 in the first and may 2025 in the last - but there is a sliight difference. 

Value from selected date

Value from selected date in prev year

 Help me understand why there is a difference!

Hi, 

Thanks for your reply! 

Your file is unfortunately showing the exact same value no matter what YearMonth I filter on, so a its a bit hard to see if ot actually solves the problem..

Hi,

EOMONTH expectes a date as first input. I do not know what data type is your datekey column.

I tried this for the second measure

VAR CurrentMaxDate = MAX('Calendar'[Date])

VAR StartDate = EOMONTH(CurrentMaxDate, -12)

RETURN 

CALCULATE(

    SUM(Sales[SalesAmount]),

    ALL('Calendar'),

    'Calendar'[Date] > Startdate
)

and it works perfectly, but I used a date column of date format. So either you use a column like that or you convert the datekey into a date with the DATE DAX Function in combination with LEFT, MID, RIGHT

If this helped please mark this as a solution and give kudos

Thanks

Best

Hi, 
Thanks for your reply! 
Its not a data type issue, 'Calendar'[DateKey] is date format
